23. Fibrocartilage

24. Fibrocartilage

25. Fibrocartilage

26. True

27. False. Fibrocartilage consists of chondrocytes and fibroblasts surrounded by TYPE I collagen and a less rigid matrix

28. Fibrocartilage

29. Chondrocytes

30. Chondrocytes. In the immature state, it is called as chondroblast and when its form cartilage cells it is called as chondrocytes.
